Hyper-V failed RRS feed

  • Question

  • Hi

    I have 2 machines running Windows server 2012 
    Hyper-V Role has been added to both machines
    Each Hyper-V has a virtual machine running windows 10

    Objective:Backup from Machine A to Machine B using Hyper-V replica feature. 

    Steps that i followed:-From Hyper-V (B), i connected to server A successfully using Hyper-V manager right pane
    -Enabled replication on Machine B
    -Applied firewall rules for TCP-In

    Question:
    On which machine, A or B, should i launch the replication wizard ?

    Whether I do it on A or B, i get the following error message: 
    "Hyper-V failed to enable replication. Hyper-V failed to authenticate using Kerberos authentication"

    Any suggestion please?

    Thank you!

  • Hi!

    Have you added the SPNs (Service Principal names) ?

    1) Open Active Directory Users and Computers (ADUC) and locate the virtual server host.

    2) Right click on the server and select properties. In the properties windows, click on the attribute editor tab.

    3) Highlight the ServicePrincipalName attribute and click on the edit button.

    4) Add the following entries if they are not present or correct them if they are incorrect. You will need to do this step for both the source and the target server. Each attribute value must be entered with the corresponding server's NetBIOS name as well as its FQDN.

    For the source server:

    Hyper-V Replica Service/SOURCESERVER
    Hyper-V Replica Service/ SOURCESERVER.DOMAIN.LOCAL
    Microsoft Virtual System Migration Service/ SOURCESERVER
    Microsoft Virtual System Migration Service/ SOURCESERVER.DOMAIN.LOCAL
    Microsoft Virtual Console Service/ SOURCESERVER
    Microsoft Virtual Console Service/ SOURCESERVER.DOMAIN.LOCAL



    For the target server (Server2):

    Hyper-V Replica Service/ TARGETSERVER
    Hyper-V Replica Service/ TARGETSERVER.DOMAIN.LOCAL
    Microsoft Virtual System Migration Service/ TARGETSERVER
    Microsoft Virtual System Migration Service/ TARGETSERVER.DOMAIN.LOCAL
    Microsoft Virtual Console Service/ TARGETSERVER
    Microsoft Virtual Console Service/ TARGETSERVER.DOMAIN.LOCAL



    The example below illustrates the Hyper-V Replica Service SPN attribute 'Hyper-V Replica Service' entry for both the servers NetBIOS name as well as its FQDN on both the source and target servers.

    See if it helps!

    Best regards,
    Leon
